Professor Julian J Bommer

My research portfolio has been defined primarily by my engagement with engineering practice and from field reconnaissance of damaging earthquakes around the world including Algeria, California, Colombia, El Salvador, Greece, Italy, Japan, Mozambique, Peru and Turkey.

The core of my research is related to the characterisation and prediction of strong ground-motion, including establishing the influence of different ground-motion parameters on structural response and damage. I have co-authored a number of widely-used equations for the prediction of peak ground acceleration and velocity, response spectral ordinates, and the duration of motion. The second major area of my research, which is effectively the downstream application of the ground-motion prediction work, is seismic hazard assessment. Topics addressed include the identification, treatment and interpretation of uncertainties, and the practice of probabilistic seismic hazard analysis.
